Wax Coating Calculator

Wax coats the wheel's surface area, which scales with the square of its dimensions, while the amount of cheese inside scales with volume, which grows with the cube of its dimensions -- so as a wheel gets larger, its surface-area-to-volume ratio actually shrinks, meaning larger wheels need less wax per pound of cheese even though they need more total wax than a smaller wheel. This is a basic geometric fact about cylinders, not specific to cheese waxing.

Two to three coats is the standard recommendation for most aging cheeses, since a single coat rarely achieves complete, pinhole-free coverage across the whole surface, and any gap in the seal is a path for mold or excess moisture loss during aging. Cheeses intended for long aging periods, a year or more, commonly get additional coats beyond the standard three for extra protection, though each additional coat adds proportionally to total wax needed and cost.

The default 0.015 oz per square inch per coat is a reasonable middle-of-the-road starting point for typical dip-coating technique, falling inside the commonly cited 0.01-0.02 oz/sq in range for cheese wax. If you're new to waxing, weigh your wax block before and after coating a wheel of known dimensions to calculate your actual coverage rate, since technique (dip speed, wax temperature, number of dips) meaningfully shifts where you land in that range.

Both matter, but diameter has an outsized effect because it contributes to surface area twice -- once through the two circular top and bottom faces (which scale with the diameter squared) and again through the circumference of the side wall (which scales linearly with diameter but is multiplied by height). A taller wheel at the same diameter adds side-wall area roughly proportionally to the height increase, while a wider wheel at the same height increases both the end-cap area and the side-wall circumference simultaneously.
